SPECIFICATION forming part of Letters Iatent No. 766,990, dated August 9, 1904.

Application iled February 4, 1901i. Serial No. 191,920. (No model.)

To all whom it may com/crm Be it known that I, CHARLES M. CHANDLER, a citizen of the United States, residing at Bayonne, in the county of Hudson and State of New Jersey, have invented a certain new and useful Improvement in Clipping-Machines, of which the following is a specification.

I will describe the machine as adapted for trimming hedges and cutting the grass around trees and the like after the operation of the lawn-mower.

I effect the clipping by a revolving shaft carrying a cutter which serves with another cutter to clip by a shearing action. I impart motion by grasping and pressing together two handles. A single gear-wheel actuated by a ratchet from an operating-lever gives a rapid rotatory motion to the revolvingblades and also through the medium of the same wheel treasures a surplus of dynamic effect in the form of momentum in a iiy-wheel carried on the instrument. The openingand closing of the shears is repeated indefinitely by a succession of' closings of the hand which supports the implement.

The following is a description of what I consider the best means of carrying out the invention.

The accompanying1 drawings form a part of this specification;

Figure l is an edge view showing a movable blade in the act of passing' the stationary blade, and Fig. 2 is a face view showing the parts at a different stage of a revolution.

The figures show the machine or clipper in the upright position which may be assumed in clipping the sides of a hedge.

Letters of reference will designate diff`erent parts, supernumerals being added when necessary to indicate smaller divisions.

Similar marks of reference indicate like parts in both the figures where they appear.

A is the main body of a part which I will referto as "stationary. Its lower portion forms a handle. It is provided with a pivot A', a stop-pin A2, a boss A3, smoothly bored, as will presently appear, and two pivots Ai andA'V. A lever B, having a handle BQ is connected thereto by the pivot A and is provided with an offset, eye, or boss atv its upper end B2 and subject to the force of a gentle spring B3.

The pivot Ai, firmly setin the body A, serves as a stud on which two rigidly-united wheelsa ratchet-wheel Gr, and a gear-wheel turn and also as a center on which a lever E is caused to vibrate, by means of a link D, which connects the eye B2 with a pivot E near the mid-length of E. A pawl II, carried by this lever, causes its vibrations to vigorously actuate the wheels G G2 with each closing motion of the handles.

M is a double-ended revolving shear-blade, and M is a pinion fixed on one face at the midlength thereof, engaged by the gear-wheel G2 and rapidly rotated thereby. This blade IVI, coacting with the fixed shear-blade A, the latter extending outward beyond A5 and havsired by rapid and clean cuts, according as the clipper is presented to the work.

The part Al performs the two functions of serving as a pivot for the lever B and holding the inner end of the fixed shear-blade A6. The pivot A, firmly set in the outer end of A, performs the two functions of a bolt-for holding thc fixed shear-blade A6 and a smooth stud on which the revolving shear-blade M and its pinion M/ can freely turn. rlhe bored boss A: forms the bearing for a short shaft J', which has at one end a pinion J, engaging with the gear-wheel (it), and at the other end a fiy ing and opening' the hand. One hand may serve alone. The cutting is effected at the passage of either blade of the revolving' part M past the stationary part. In some work it may be revolved idly a few times at intervals to acquire a higher rotative velocity.

I attach importance to the fact that the rcvolving shear M is two-bladed because the two parts balance each other; that the part A is formed separately from the other fixed parts and rigidly united thereto, because it makes a strongself-contained device with facility for assembling and separating', and that the fly-wheel J 2, geared to turn at a high velocity, is near the handle, because its weight i is more easily supported.

ing an offset at a, effects the shearing' de-` The operation is effected by alternately clos- IOO I attach importance to the construction of the part A with an oi'set t6 because it allows the revolving shear M to be plane and presents the iiXed shear-blade adjacent to the plane thereof while it is in the effective part of its revolution and provides ample clearance While it is in the ineffective portion.

Modifications may be made without departing from the principle or sacrificing the advantages of the invention. I have in my eX- periments made the parts of sheet-steel, with the thick portions Welded or brazed thereon. I propose to make some of the parts dropforgings or malleable castings.

I claim as my invention- A clipping-machine comprising a portable
